产品描述: | Adezmapimod (SB 203580) hydrochloride is a selective and ATP-competitive p38 MAPK inhibitor with IC50s of 50 nM and 500 nM for SAPK2a/p38 and SAPK2b/p38β2, respectively. Adezmapimod hydrochloride inhibits LCK, GSK3β and PKBα with IC50s of 100-500-fold higher than that for SAPK2a/p38. Adezmapimod hydrochloride is an autophagy and mitophagy activator |
靶点: |
p38:50 nM (IC50);p38β2:500 nM (IC50) |
体外研究: |
Adezmapimod hydrochloride (用 0-30 μM 预孵育 1 小时并在 20 ng/mL IL-2 存在下培养 24 小时) 可防止 IL-2 诱导的原代人 T 细胞、鼠 CT6 T 细胞或 BAF 增殖 F7 B 细胞的 IC50 为 3-5 μM。 Adezmapimod hydrochloride 阻断 PKB 磷酸化 (IC50 3-5 μM)。Adezmapimod hydrochloride 在 CT6 和活化的人 T 细胞以及 IL-2 反应性 BA/F3 F7 B 细胞中以剂量依赖性方式抑制 Ser473 的磷酸化。 Cell Proliferation Assay Cell Line: CT6, BA/F3 cell line F7, and PBMC/T cells Concentration: 0-30 μM Incubation Time: Preincubated with 0-30 μM SB203580 for 1 h and cultured for 24 h in the presence of 20 ng/mL IL-2 Result: Prevented the IL-2-induced proliferation of primary human T cells, murine CT6 T cells, or BAF F7 B cells with an IC50 of 3-5 μM. Western Blot Analysis Cell Line: CT6 cells, activated human T cells, and BA/F3 F7 cells Concentration: 0-30 μM Incubation Time: Preincubated with 0-30 μM SB203580 for 1 h before stimulating with 20 ng/mL IL-2 for 5 min Result: Inhibited the phosphorylation of PKB at Ser473 in a dose-dependent manner. |
体内研究: |
Adezmapimod hydrochloride (5 mg/kg/day; 连续16天每天腹膜内注射; 雌性无胸腺 Nu/Nu 小鼠) 处理与平行处理的 p38TM 肿瘤相比,p38WT 肿瘤的肿瘤负荷明显更小。 Animal Model: Six-week-old female atymic Nu/Nu mice CAL27 p38WT and p38TM tumors Dosage: 5 mg/kg/day Administration: Intra peritoneal injected daily for 16 consecutive days Result: After 2 weeks treatment, CAL27 p38WT tumors were significantly smaller; CAL27 p38TM tumors were not affected by the p38 inhibitor (n=10). |
